I'm looking to expand my storage. Can you sifu's recommend reliable SSD enclosures and drives to be used with my M4 Mac Mini?

I decided I didn't need the blazingly fast speeds and went with a portable SSD (Lexar SL600) instead. It's supposed to give me up to R/W speeds of up to 2000MB/s but when I tested it today through Blackmagic Disk, I'm only getting about 900+.
How to maximize and increase the speed? |

QUOTE(soonwai @ Dec 2 2024, 04:10 PM) 900+ using the front ports? Not the front. Am using one of the 3 available TB4 ports at the back of the M4 Mac Mini. The back ports should give me better speed? Let me switch and try it with the front ports instead. |

QUOTE(soonwai @ Dec 2 2024, 05:43 PM) Yah, front only 10Gbps and back should be 20Gbps for USBC. Dunno why you're only getting 900MBps. Hmmm ini tak bagus...... could possibly be the cable problem? I'm using the Cable that came with the SSD drive; maybe that's not a TB4 cable so that's why? |

QUOTE(giggs_509 @ Dec 2 2024, 07:34 PM) A note for Macworld readers: Somewhat confusingly, Macs support 20Gbps USB, but only if the SSD is USB4. USB 3.2×2 20Gbps SSDs such as the SL600 will perform at 10Gbps using the USB 3.1 gen 2 protocol on Apple computers. Ah, so this SL600, although it says can support up to 20Gbps, it won't because I don't have the hardware that can support it is it? Sorry ah, tech n00bie here https://www.pcworld.com/article/2239717/lex...e%2520computers.  "A note for Macworld readers: Somewhat confusingly, Macs support 20Gbps USB, but only if the SSD is USB4.

But here's the thing, the new M4 Mac mini ports are USB4 isn't it so it should be giving me the max speeds, no? This post has been edited by tinkerbel: Dec 2 2024, 09:44 PM |

QUOTE(yvliew @ Dec 2 2024, 10:21 PM) Mac does not support USB 3.2 Gen 2x2 protocol which I just learn couple days ago. That's why my 20gbps portable ssd never reach 2000MB/s. Mac only support TB3,4 USB4 and USB 3.2 Gen 2 10gbps. I thought the 2 front ports on the M4 Mac Mini is USB 3.2 Gen 2x2 protocol.... which reminds me, I should test the speed again using the front ports but OMGAWD I just sorted all the cables!  |

As a follow up to the SL 600, it's giving me the same speeds of about 900+ on the front ports - I'm not getting the 2000mbps speeds as I expected it to be but ah well...... should be suffice for my needs for now.

QUOTE(Skeuomorphic @ Dec 4 2024, 12:38 PM) its because macs' tb4 ports dont support usb 3.2 2x2 speeds of 20 Gbps. in fact very few pcs do. it came pretty late into the usb lifecycle and manufacturers already started adopting USB4 instead. you can only get 10 Gbps with usb 3.2 gen 2 Thank You! I've now learnt something You can see here the example as given by kingston for their XS2000 external ssd which supports usb 3.2 2x2  only way to get over 10 Gbps r/w speed is by using a gen 4 nvme ssd in a USB4/tb3/tb4 enclosure  |
